Abstract
The acid catalyzed—effluent refrigerated alkylation of hydrocarbons in a shell and bare tube type alkylation reactor is improved by providing the bare tubes with internal inserts capable of increasing turbulence and mixing of refrigerant within the tubes whereby heat transfer in the process is enhanced.
Claims11
In the acid catalyzed—effluent refrigerated alkylation process wherein a refrigerant is passed through bare tube in an alkylation reactor the improvement comprising providing the tubes with internal inserts capable of increasing turbulence and mixing of refrigerant within the tubes whereby the heat transfer of the refrigerant is enhanced.
In a process of alkylating is oparaffinic hydrocarbon with olefinic hydrocarbons in the presence of an acid catalyst in a reaction zone to form alkylate wherein a mixture of hydrocarbons with acid catalyst is withdrawn as effluent from the reaction zone and separated into an acid phase and a hydro-carbon phase and which separated hydrocarbon phase is refrigerated and passed through tubes located in the reaction zone for indirect heat exchange with the hydrocarbons and catalyst, the improvement comprising providing the tubes with internal inserts capable of increasing turbulence within the tube whereby the heat transfer coefficient is enhanced.
